SyntaxError: invalid syntax (windows)

I'm a total newbe to scripting not to mention python. However I was able to
successfully create a telnet script to initiate login, initiate tftp, exit,
exit, confirm and close session. Frustrated, possibly causing my own misery.
I replace the sript the script with the standard example.

I have also notices some other slight differences: this is my original
script that runs and completes but only if I comment out print. Also tried
to run debug without success in windows again this worked fine in linux. To
run this script in linux I also had to remove the b syntax in the "b" in the
perentesis

In python 3.X, print is a function call
print(tn.read_all() )
with lots of formatting and line-ending features

In python 2.X, print is a statement:
print tn.read_all()

If you want one script to work for both Windows and Linux, then you
should probably
be running the same version of Python on each. At least both versions
should be on
the same side for the Python 2.x/3.x version change.

Gotcha, I got started from the telnet example listed in the docs. The linux
install was via yum and installed 2.x instead. That explains it. Althought
print (tn.read_all () ) runs in 2.x on linux.

I have another problem maybe you cna help me with. My telnet output
jibberish in windows: I cna parse some of the output for results but is
there anyway to get rid of the jibberish. (looks like hex but I'm not sure)

I can only use this tn.read_until(b'whatever string') Is this whats causing
the output? the b switch. seems like I don't need it in linux. is that
binary?

They look like control sequences for a terminal.

"32-bit character-mode (subsystem:console) Windows applications don't
write ANSI escape sequences to the console. They must interpret the
escape code actions and call the native Console API instead to
accomplish the proper result. If you do write the sequences directly,
all you'll get is the text of the sequence on the screen, not the action
intended."

I mostly see a crazy mixture of ESC [ row , col H cursor position
commands. For you app, parse out and ignore the codes not skipped by
..read_until calls.
